PMT contact lens P.Kooijman, Nikhef KM3NeT, General Meeting, 20 February, Catania
Why At present we have received from ETEL and Hamamatsu concave-convex PMTs Manufacturers say the front glass is very expensive Thin glass curved front face works just as well If we go that way can we still have the concentrator ring?
Plastic lens Possibility for plastic lens Glue to the front face with 45 degree edge Radius of sphere Radius of PMT front face
Manufacture? 92% (in lucht gemeten; altijd reflectie) Zeonex 480R Injection Molding! Fosta-Tek Zeon Europe GmbH 3.7% per interface (1 naar binnen, 1 naar buiten) Unofficial 5 /unit + 20k /mold cost reduction for PMT-unit For 8 mm thick samples (measured in air) Quotations requested
